Imgix download transformer for Imager X

A transformer for Imager X that uses Imgix for transforms, but stores the transformed images locally.

Requirements

This plugin requires Craft CMS 5.0.0 or later, Imager X 5.0.0 or later, and an Imgix account.

Usage

This plugin is a hybrid between the default craft transformer that uses GD or Imagick to generate image transforms locally on the server, and the imgix transformer that uses Imgix. It uses Imgix to transform the image, but downloads and stores the image locally on the server.

Why not just use imgix? Saves you some $$$.
Why not just use craft? Saves you a lot of CPU cycles and memory, and you're not limited by your server configuration.

All configuration is done through Imager's standard configuration, just like you would when using the craft and imgix transformers. This transformer will use the configuration for each where appropriate, so if you run into problems test that your configuration works for those transformers.

To activate the transformer, set the transformer config setting to imgixdownload:

'transformer' => 'imgixdownload',

Cave-ats, shortcomings, and tips

The biggest cave-at by not letting Imgix serve the images through its CDN, is that auto: format doesn't work anymore. You'll have to serve up different formats manually, preferably using <picture>, just like you would if you used local transforms.

Even though transforms aren't done on the server, there will still be some latency while waiting for Imgix to deliver the image. So just like when using the craft transformer, you'll benefit from configuring automatic generation of transforms for your project.

External storages and optimizers work with this transformer exactly like it does for craft.

Imager will use your imagerUrl config setting when serving images, so you're free to add your own pull CDN if you like.
